I agree with the above. Check out Apistos (Rams actually are a type of Apisto)
Actually, rams are in the genus mikrogeophagus (or papillochromis, depending on who you ask), and apistos are in the genus apistogramma. They are very similar in terms of habitat preference, feeding, spawning, etc. with the exception of some apistos that are harem spawners.
I'd say go for apistos, if you can find some. After you keep them, rams just seem kind of... common, even though I'll always like them too.
